Figure 4.5 Constant resistance mode
4.1.2.1 Standard fixed resistance mode
Press the CR button, the load shows "STANDARD RESI = xxxxxxxxΩ", prompts the current set resistance, then
press the numeric keys and decimal point keys on the panel, enter the desired constant resistance value from high
to low, and press the Enter key to confirm , Load into the standard resistance mode.
In this case, if the input status is OFF, the upper right corner of the display panel will display "OFF". To change
the input status bit, press the On / Off button. The "CR" or "Unreg" "CR" means that the expected resistance value is
reached. If "Unreg" means the load can not be adjusted to the preset resistance value correctly, check whether the
source under test is properly connected and turned on or whether the source under test can output the preset
resistance Current.
At this time, if you want to fine-tune the set resistance, you can use the upper right corner of the rotary
encoder, clockwise to increase, counterclockwise to reduce. The bottom right of the display panel is for setting the
resistance value indication. One digit indicates the cursor, indicating that the current fine adjustment fineness is 1
unit in the current position. If the user wants to change the fine adjustment, the rotary encoder can be pressed
down , Rotary encoder contains a button, each button is pressed, the prompt cursor will move a grid, in order to
achieve the adjustment fineness adjustment.
4.1.2.2 Loading and unloading fixed resistance mode
The principle of loading and unloading mode, please refer to 4.1.1.2 instructions
In the standard constant resistance mode, press Shift + 1 (V_Level) key to enter the load and unload constant
resistance mode, the load display "ONSET VOLT = xxxxxxxxV" prompts the current load voltage, at this time you can
press the number keys and decimal point keys on the panel, Enter the required load voltage value from high to low,
and press Enter key to confirm, the load display "OFFSET VOLT = xxxxxxxxV" prompt the current unloading voltage,
at this time you can press the number keys and decimal point keys on the panel, from high to low order Enter the
desired unload voltage value and press Enter to confirm, the load enters the load unload constant resistance mode.
If the input status is OFF, the upper right corner of the display panel will display "OFF". To change the input
status bit, press the On / Off button. In the upper right corner of the display panel, "CR_UN" or "Unreg" is displayed
and "CR_UN "Indicates that the desired resistance value has been reached. If" Unreg "indicates that the load can not
be adjusted to the preset resistance value correctly, check whether the source to be measured is correctly
connected and turned on, whether the voltage is within the normal range, or whether the source under test can
output the pre- Set the resistance to absorb the current value.
Pressing Shift + 1 (V_Level) while loading / unloading resistor mode, the load will return to the standard
constant resistance mode.
